When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, you can make far more than 100% on a really good stock. Long term Sonic Automotive, Inc. (NYSE:SAH) shareholders would be well aware of this, since the stock is up 260% in five years. In contrast, the stock has fallen 9.9% in the last 30 days. This could be related to the recent financial results, released recently - you can catch up on the most recent data by reading our company report.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During the last half decade, Sonic Automotive became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Sonic Automotive, it has a TSR of 291% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

Sonic Automotive shareholders gained a total return of 3.3% during the year. But that return falls short of the market. It's probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 31% over five years. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Even so, be aware that Sonic Automotive is showing 3 warning signs in our investment analysis , and 1 of those can't be ignored...
